Well if I understand what your asking here, it sounds like you are asking about what are commonly refered to as templates.
I don't know how other people do it but it can be approached in many different ways with many different things included.
When I begin a new CAM file from an existing model. I use a template file that brings into the new file all of my standard tools that reside in my carousel on my machine. I also have several defined tool paths that have been proven to work efficiently with speeds, feeds, DOC, they also are imported.
I am sure other people template many other things but nearly anything you want is availabe to be made and used as a template.
